ELECTRIC IGNITION DEVICE.

Specification of Letters Patent.

Patented June 29, 1909.

Original application filed April 4, 1906, Serial No. 309,736. Divided and this application filed November 23, 1906. Serial No. 344,702.

To all whom it may concern:

Be it known that I, THEODORE HUBERT, a citizen of the United States, and resident of New York city, borough of Brooklyn, New York, have invented certain new and useful Improvements in Electric Ignition Devices, of which the following is a specification.

Thifisigpplication is a division of my application April 4, 1906, Serial No. 309,736, for improvements in electric ignition devices, and the object of my invention is to cause the movable member of the primary magneto circuit to-cause the make and break in a separate circuit.

My invention comprises a magneto having make and break contacts and means tooperate the movable member thereof, with a contact for a se arate circuit arranged to be made and bro en by the action of said movable member of the magneto contacts.

- The invention also comprises the novel arements and combinations of parts hereter more fully set forth and then pointed out in the claims.

Reference is to be had to the accompanydrawin'gs forming part hereof, wherein igure 1 IS a sectionaldetail view of a ortion of a high tension magneto adapted for use in connection with my improvements, and Fig. 2 is a erspective view illustrating diagrammatically the circuits and devices of my invention.

The magneto 1 may be of any well known construction of high tension magnetos in which the armature 3 is mounted to rotate within usual fields (not shown,) and the primary winding 5 of the armature is shown connected with a metal plate 6 rigidly carried by the armature b'ut insulated thereas by insulation 7, and engaging a frame of the magneto.

" At 9 is a contact in the primary circuit supported by and insulated from the frame of the magneto, and at 10 is a movable contact shown carried by a pivoted arm 10 supported by the frame of the magneto and which may be grounded through the frame with which one terminal of the primary winding may also be grounded. The contact 10 is o erated by a cam 1 1 carried by the magneto s aft 4, said cam being shown provided with two projecting portions to engage a roller 12 of arm 10*, a coil spring 10 SGIVlIlg to pull the arm toward the cam, all whereby,

" when the primary magneto circuit is closed and opened the discharge in the secondary armature winding 13 will be produced in well knoun manner in high tension magnetos. To control the magneto primary circuit at will I provide a switch indicated at 14: in a branch line 15, as hereinafter explained. The secondary magneto winding 13 is shown connected by a screw 16, insulated from shaft 4, with a spring pressed contact 17 in circuit with a binding post. 18 shown carried by an insulated cap 19 secured upon the magneto framel the ,;'v 30st 18 being snown connected by wire 20 ig. 1) with a suitable distributor contact adapted to engage a contact 22 in the secondary circuit, the opposite'terminal of the secondary winding being grounded through the magneto frame as indicated by wire a in l'ig.

In Fig. 2 I have shown means whereby :1 battery circuit and vibrator coil or coils may be used in connection with the magneto and its oircuits,and wherein when the battery circuits are being used the magneto circuits may be cut out, and vice versaa l T 0 this end I have shown the wire 15 of the primary magneto circuit connected with a binding post 6 and the wire 15 of said circuit connected with a binding 10st 0, wires 15 15 connecting said posts and a, respectively with contacts (2 and e. The circuit through contacts (1 and e is adapted to be opened and closed by the contact or switch ii that is shown secured to an insulating block 45 to be operated by a suitable handle, whereby whenthe circuit is closed at (Z, c, the current will flow from brush 8 to 15, 15*, (Z, 14, e and 15, the contacts 9 and 10, thence through the nimary coil of the magneto, back [0 brush 8.

I have also shown the secondary circuit of the magneto arranged to be opened and closed with the opening and closing of the primary circuitthereof, and to this end the circuit, instead of running direct from post 18 to the contact by wire 20, as in dotted lines in Fig. 1, the wire 20 leads to contact f and wire 20 leads from contact 9 to contact 22, and switch 25 is adapted to close the circuit between contacts f and g at the time that switch 14 closes the circuit between contacts (2 and e, as in dotted lines in Fig. 2. Switch 25 is shown secured to insulating post to ground, as

45 so as to be operated coincidently with switch 14'. Thus, when switch closescircuit between contacts f and g the secondary circuit of the magneto will be from the secondary winding through post 18, wire 20, contact f, switch 25, contact 9, wire 20*, contact 22 and thr ugh contact 22, and wire a, at an engine frame A, and thence through the frame of the magneto, back to the secondary winding, as by wire a in Fig. 2.

A separate circuit for a battery, and the primary and secondary of vibrator coil and circuits, are arranged as follows: From the battery 46 the wire 17L leads to the primarv coil 47 and thence by wire 2', contact j, and vibrator spring through wire Z, contact'm,

and from an associate contact a through wire 0, post p and wire o to the spring or contact 48 adapted to make and break the circult with movable member 10 which member leads thence back to the battery, as by ground through the mechanism, indicated in Fig. 2 by wires 1* and s to ground. Switch 14: is adapted to open and close the circuit through contacts at and n and when in such position the rotation of cam 11 will cause the primary battery circuit to be made and broken at contacts 10 and &8. Thus it will be seen that the time of the make and break between contacts 10 and 48 caused by the lifting. of contact 10 by cam 11 will be slightly retarded with respect to the make and break between contacts 9 and 10 of the primary magneto circuit, so that, for instance, when an engine provided with my improvements is being started by means of the battery circuit the spark will be slightly retarded with respect to the timeof the spark produced by themagneto, because the latter occurs at the break between contacts 9 and 10, and the battery circuit break does not occur 'until after the cam has left arm 10 and spring 10 has pulled the latter from contact 48, thereby making it more safe to the operator,'as respects a back kick from the engine, to start the engine with the battery clrcult. The secondary winding 49 ot the vibrator coil is grounded at one terminal as through the mechanism, or through wire h in Fig. 2, and the wire 25 leads from the other terminal to the contact u to be engaged by switch 25 to place said winding in circuit with contact 22, through contact 9 and wire 20 when switch 25 is in the position shown in Fig. 2. Thus, when the battery primary circuit is closed by switch 14 at contacts m, n, the battery secondary circuit will be from ground or the mechanism through winding 49, Wire t, contacts a and 9, switch 25, Wire 20, contact 22, and through contacts 22, etc, and Wire (1 back to ground. I

From the foregoing it will be'understo'od that by simply turning switch 45 for'contacts d, e, andf, g the magneto priniaryand' mary and secondary circuits will be broken,

and that by placing the switch in the position shown in full lines in Fig. 2 the magneto primary and secondary circuits Will be broken while the battery primary and secondary circuits will be closed for such igniting devices, and thus, the same cam 11 and movable member 10*, serve for making and breaking the primary magneto circuit at 9, 10, and for making and breaking the vibrator coil priand secondary at 10*, 4S, and that only one of said primary circuits will be operating at one t im In this application I do not claim the details of construction of the magneto shown and described, as they are embraced in my foresaid application, Serial No. 309,736, and also shown in my application, Serial No. 344,703, filed Nov. 23, 1906.

made and broken by the action of said movable member of the magneto contacts.
